Question

A sample of blood pressure measurements is taken from a data set and those values (mm Hg) are listed below. The values are matched so that subjects each have systolic and diastolic measurements. Find the mean and median for each of the two samples and then compare the two sets of results. Are the measures of center the best statistics to use with these data? What else might be better? Systolic: 134 155 112 99 138 150 103 97 102 127e Diastolic:8974 88 7 51 60 78 53 76 81 Type integers or decimals rounded to one decimal place as needed.) ind the medians. The median for systolic is 119.5 mm Hg and the median for diastolic is 76.5 mm Hg Type integers or decimals rounded to one decimal place as needed.) Compare the results. Choose the correct answer below. A. The mean and median appear to be roughly the same for both types of blood pressure. B. The mean and the median for the diastolic pressure are both lower than the mean and the median for the systolic pressure O C. The mean is lower for the diastolic pressure, but the median is lower for the systolic pressure. D. The median is lower for the diastolic pressure, but the mean is lower for the systolic pressure

Answer 1

Option D is correct.
Since the systolic and diastolic blood pressures measure different characteristics, a comparison of the measures of center doesn't make sense.
